- use to adapt the'same for transportation and a citizen of the UnitedSta Be-it known that I, PHILIPPE on Gunner, and a rest dent of Boston,county of Sufio k, and State oiMassachusetts, have invente'd'certam newand useful Improvements in Type-WritinF Machines, of which thefollowing'is a ful clear, and exact description.

This invention relates more particularly to the esca t mechanism .ofE afront strike or ot ei-Srisible typewriting machine which may be madecompact when not in other purposes.

One of the principal objects of the invention is to provide a smallcompact portable typewriter in which the keyboard is mounted u n a framepart or member which is slid'aheld to the main frame part or memberofthe machine and is movable from a normal operative or extendedposition to an abnormal and more compact one when not in use, and at thesame time so construct the frame or support that it ma form an inelosingand protecting case .or the escapement mechanism and, the keyboardwhen-in a compact position, and whiclrmay be opened to adapt thetypewriter keys and other parts tobereadily accessible for oper ation inthe usual way.

Another object of the invention is to provide atypewriter which .is verycompact when not in use and which is so constructed that it may bereadily transported as a part of a rsons luggage, or for other purposes.

Qt er objects of the invention areto provide a typewriter in which thesupport may i be variousl constructed whether asavcase inf-Which al themechanism is mounted in order that a separate carryin case may'bedispensed with, or wherein .t 1e framemay beconstructedsinmly as amounting" for the dili'e rent mechanisms so that-the typewriter l may beplaced in a separate and; independent case, if desired; to, provide asimple and efiective mechanismto control the feed of the carriage; toprovide a writing machine wherein the platen carriage and part of theescapement mechanism may be given different shift movement-sic!different type carried' by the different type-barsfwithout separatingthe escapement' parts; and to pro vide means whereby an a normalmovement of the platen. carriage to an inoperative Specification orLettctl Patent.

position may be automatically eflected when the keyboard is moved fromits normal operative position to a compact position, and during suchabnormal movement of the platen carriage have the parts of theescapement mechanism maintained in operative relation. U

' A further ob ect of the invention is to provide -means whereby theinclosing case of.

the mechanism may be. logked and the. parts so constructed that the.eseapement mechanism is entirely protected and inaccessible when not inuse.

A still further object-of the invention is to provide a typewriterwherein the-platen carriage and the keyboard may have a relativemovement from a normal operative position to a more compact one or viceversa, and duringsuch movements have the connection between the keys andthemeans controlling the escapement mechanism maintained without anydisconnection or disorganization.

With these and other objects in view, the invention will be hereinaftermore particularly described with referenceto the accom- 'panying,drawings,which form a part of this application, and will then beintedoutin the claims at the end of the escrip- In the drawings, Fi ure;1 is a longitudinal section, partlyin ovation, of one form of machineembodying the invention, showing the escapement mechanism in positionfor operation when one of the keys is de-. pressed.

' support for the different parts of the typewriter may be variouslyconstructed As shown, the case or frame 10 comprises a mainsubstantially box-like frame part 11,

havin a base 11, a rear wall 12, a partially open ront wall 12*, andside walls 13. The base 11 may be continuous or may have two offsetparts 13 and 14, as shown in the drawings, said oflset parts beingprovlded with the usual supporting rubber feet 15, if (lcsirecll A topor cover member 16, is hinged at\17- to the upper part of the rear wall19., and at the end opposite the hinge 17 oisaid cover member or top16'is a front plate or member 18. This member 18 is hinged at theforward edge of the top 16, and is adapted to inclose the open front orspace19 of the main part, member or section 11. At the front'portion ofthe main frame part is'a keyboard member or frame part 20. This framepart 20 is slidably held to move horiz-zmtally within the main member 11from a normal operative and extended posi- .ion, as shown in Fig. 1, toan abnormal compact one, as shown'in Fig. 4. The frame part or member 20may have a substantially box-like form of considerable less height andlength than the main frame part 11,

and said frame part 20 has a base 21 on which may be supportin wall 23having an exten ed portion, as 24, by which the frame part 21- may bemoved inwardly and outwardly and a top portion or plate '25. The base 21of the frame part 20 is adapted to slide forwardly and rear wardly onthe offset base art 14 and has its side Walls 26 provide These slots 27are each adapted to be engaged by the shank 28 of a pin or bolt 29, andengagin the threaded end of the shank 29 of each bo t is a thumb nut 30.The shank of thu. bolt 28 base square portion to fit the slot 27 andforms a bearing portion and guide forthe sides of the frame part 20-.durin its horizontal sliding movement. Each bolthas an enlarged head31 so that by tightening the thumb nuts 30 at each side feet 22, a frontwith slots 27.

of the machine the extensible and slidable frame part 20 may be heldeither in its extended normal position or in its compact abnormalpositi0n. The front plate 18of the inclosmg case is adapted to rest aainst the upper surface of the top 25 of the rame part 20 when in acompact condltion, and mounted upon the part 18 is a lock 32, as forexample a lock such as is employed on desks and, which is accessible bya key through an opening or keyhole 33, whereby the tumblers of thelockmay be disenga ed from or made to engage a slot 34 or ot er holdingmeans in the top 25 of'the framepart 20 to lock said frame art a ainstaccess except b means of the ey. he front part 18 may portion the casemay have end pieces, as 36, to adapt the laten carriage, as will bepresently descri d, to have free movement transversely of the machinewhen in use. The sideor end pieces or members 36 are hinged to the rearwall 12 and are adapted to inclose the cutaway portions 37 of the sidewalls of the main frame part 11. The side pieces 36 have beaded orrabbeted edges and the top member 16 may also be provided with arabbeted or beaded edge so as to lock the end Biecesor members 36 m aclosed position w en in the position shown in Fig. 4.

also provided with a handle, as.35, forcarryingpurposes, and at the rearOn the frame part 20 is mounted the keyboard 38. The keyboard lnay beofthe usual standard or universal kind. wherein a plurality of banks orgroups of keys are arran (1, each operating individual type, such ban sbeing in three or more sets, according:

to the number ofprinting characters, and

guided in a bushing yoke or head 42 to which is pivotally connee-ted thearm 43 ofa bell-crank lever 44. The bell-crank lever 44 is pivoted .at45 to a lug or bracket 46 extending inwardly from the frame part 20,said part 46 extending in-, wardly from the top 25 for two banks or rowsof key-operated levers and from the front plate 23 of the frame part 20for the third row of key-operated levers. The keyoperated levers 44 havea pin-and-slot connection with the stems 40'and under each head 42 is arubber or other strip 47 to take the shock due-tothe return movement ofthe rods 40. The arms 48 of the key-operated to a1ink56, said link 56being 1 type b sired form, and is adapted when a key is depressed toforce theupper arin 53 of one of the leverg52 inwardly. The devers' 52are all'x mounted. on a common pivot-rod 54 which is curved according tothe arrangement of the levers 53 and the parts actuated thereby.

The arm 53 of each lever 52 is pivoted at'55 pivoted at 57 to a In 58 ofa type block or ead 59. Each lock has a plurality of charactersor type60 thereon, in this case three characters because theme is double caseshift, one, of said characters representing the lower' case type,

another character the upper case type, and the third character or type,figures, punctu'ation marks, etc, this arrangement being variedaccording to the construction of the machine. The t ope heads or blocks59 are held 1 to bars 61. ach bar 61 is guided to slide in 1 a bearing62 and is normally forced in one y direction by a spring 63, one end ofwhich v the wor I 61? are thus substantlally radially arranged is heldto the forward end of said bar and the other end to a part of the maincasing or frame. The bars 61 are held in slots and overthe bars is afinishing and a retaining plate 64. The bars61 are arranged in a curvedpath'so that as they are propelled or "forced-inwardly they will movetoward the prlntin goint to impress a character upon eld upon the platen65. 'The bars with respect tothe pnilttingpoint so that all the ty e ofall the'bars as each one .is forced inwardly through theij pvement ofthe levers52, links 56 and bars 61 on the depression of the keys 39 willstrike at the same point on the work sheet. This arran ement of thetype-bars is not broadly new. nstead ofthe type-bars having a horizontalslidin movement they may have an. upward an rearward movement as iscommon in most standard visible writing machines.

The banks or groups of keys 39 and the bell-crank levers 44 all movebodily with theframe'part toward or away from the boardas a unit to bemovedinto the main t e-bars and the platen carria e 65 and, uringsuchmovement said ban s of keys,

and levers maintain a fixed relationwith respect to each. other, thus'adaptlng the keyframe member to make the machine compact or to bemovedto an. extended operative position at'the will of the operator. r The paten 65 is'rotatably mounted upon endpieces or brackets 66 61? acarriage 67. The plateh carriage 67 has a base 68 which isconstructed'to move transversely of the ma chine and may be guidedingrooves in a car- H'age bed- 69. The carriage bed 69 is held to movevertically at its ends for case shift as 'will be presently described.-The platen carriage may have the usual parts mounted usual constructionand has its shaft 75 .These lovers 83 and thereon which coiiperate withthe platen, such as line-spacing, ribbon vibratin mechanism and otherfeatures usually emp oyed in connection with typewriting machines. Someof the parts which are common to the ordinary typewriter are not shownand some features are shown in part and others simply sufigested. Theremay be one or more feedro only yne beingl shown,'as roll 70', andadapted, toguide' t e paper or work-sheet about the platen is a paperapron 71. Paper fingers 72 are held upon a transversely ex-' tending rod73 which may be graduated or not, as desired, and these aper fingers areadapted to be held in various positions. by means of thumb-screws 74 sothat dillerent .widths' of about the p aten 65. The platen may be orojecting beyond the end bracket 66, an 'on each end of said shaft maybe a knob 76 by constructions may be employed. As'shown,

aper may be properlygmlider:

the platen carriage is given a vertical movement Tor .upper caseprinting, and in this particular machine the platen carriage has twoshift movements to. adapt the type heads each to have three charactersthereon. The

normal operative position of the platen with respect to the type on theblocks 59 i such that the rinting point is directly inline.

' with the ower type character on each type block, the normal positionof the platen'and carriage being obtained by mechanism presently to bedescribed. The carriage bed'69 isjheld to vertically movable partsorslides 77 These slides 77 have a dovetail connec U011; 79 locate frame.part 11, so that the carria e and laten may be moved vertically an uniormly ,iguided at both ends during such vertical movement. A pin 80extends inwardly from .each part 77 of the :platen carriage and adaptedto engage said pins are arms 81 and 82. The arms 81 and 82 are arrangedin sets, there being an armlof each set located '105 as 78 with theenlarged parts or guides on opposite sides of the main at opposite sidesof the machine toimpart unifprm vertical movement to the platencarriage. The arms 81 and 82 'are slotted to permit relative movementbetween the. arms 81 and 82 and the carriage for the different armsBlare connected to bollcran \"ers 83 and the arms 82 to bell-crank theboll-crank leverson opposite sides of the machine may be moved in pairs,said rods 85 and86 having hear ngs in lugs 86 on the '120 shiftmovements of the platen carri e. The I frame base part 13. The arms 87oflhe bell-crank levers 83 and thearms 88 of the bell-crank levers 84'are of such lengths, that the same movement of said arms are adapted toimpart different shift movementsto the platen carriage according to thespaclng between the type on the blocks or heads 59.

The bell-crank levers 83 and 84 are each connected by a wire link 89 andthese wire links are connected to key-operated bell-crank levers in thesame Way as the links 50 are connected to the bell-crank'levers 48. Two

shift keys 90 and 91, Fig. 7 are located on one side of the machine, andthese keys when depressed will operate the bell-crank levers 83 and 84to impart different shift movements to the platen carriage as alreadydescribed.

The links 50 and 89 are guided in a transversely extending bar 92, therebeing an ap erture in 'said bar for each link so that the links areproperly held spaced apart. The bar 92 is held to one end of links 93and these links at their other ends are pivotally held at 94 to thesides of the frame part 20. The ends of the bar' 92 are guided in slots95 of arms 96. These arms 96 are located on 0p,- posite sides of themachine and are'pivotally held at 97 to lu s 98 extending upvwardly frompart 14 o the mainframe part 11. The upper ends of the arms 96 arepivoted to links or connectin rods 99 and these links 99 are pivoted att eir inner ends to arms 100. The arms' 100 are held to studs 101,v Fig.8, and on said studs 101 are eccentri cs 102 so that as the links 99 areforced inward the arms or cranks 100 will rotate the eccentrics 102; Inthe compact position of the parts as shown in Fig: 4, the'printing pointof the platen is below the plane of travel of the lower case type on thetype heads or blocks. When the keyboard frame part 20 is moved outwardlyto a normal operative position, the transverse bar 92 by reason of itsconnection with the links 93 will force the arms 95 downwardly from theposition shown in Fig. 4'to that shown in Fig. '1. .This downwardmovement of the arms 96 will force the links 99 forwardly and suchforward movement of said links 99 will rotate the eccentrics and thiswill elevate the carriage and platen to its normal'operative positionwherein the printing point of the platen is in a direct line with thetravel or movement ofthe lower type character of the type-bars." In thisposition the platen may be shifted for the different type characters asalready described, and; may be restored to its normal position on therelease of the shift keys either by gravity or 'by spring or springs,not shown, for that purpose. During the compact movement when the key-'board frame 20 is moved inwardly within the case such movement willelevate the bar 92 by. reason of the-link connections 93, and

this will raise the arins' 96 and force the links Or arms 99 inwardlythereby rotating the eccentrics 102 which will permit an abnormal movement, of the carria e and platen allowing the same to drop be ow the pathof the type to an inoperative position. During this compact movement thewire link connections are raised by the bar 92 and are maintained intheir proper relation by reason of said bar 92 and without liability ofA connection is thus becoming entangled. always maintained between thekey-operated levers and the the shift keys and the parts operatedthereby, and during the extended and compact movement of the keyboardthe normal and abnormalposition of the platen and carriage isautomatically effected through the action of the eccentrics 102 and theconnection between saideccentrics and the keyboard frame part 20 asalready described.

type-bars as well as between A special construction of escapementmechanism is employed for controlling the letter-feed movement oi theplaten carriage. Each type ba'r operating iever52 is provided with aprojecting part 1035and this projecting part overlies a universal bar104. The

"of the rear-wall 12 of the main frame part un1versal bar is. curved toconform to the arrangement of the type-bars, and said uni 11 orotherwise, and interposed between said wall and a collar 111 on eachrod'110 is a spring 112 tending normally to force each rod 110 forwardlyto move-the universal bar against-the levers 52. Therods 110 are Iconnected together by a' rod 112 and mounted to move with sa id --;rodis any upright arm 113. This arm 113 is formed in. two

parts 114 and 115. The part 115 is pivoted at 116 :9 th; part,114-tomove therewith, there being a shoulder 117 to prevent movement of thepart relative to the part 114 I except inone' direction, a spring 118being provided to hold the two parts of the arm 113 normally ina'linemen't. The part 115 'is adapted to engage an arm or projectingpart 119 on a pivoted escapement dog or detent-120Q The'detent 120 hasdogs 121 and 122 and is adapted to engage the teeth of'a rack 123extending downwardly from'the platen carriage base 68. pivotally held toa fixed rod 124 and the The-detent 120 is I rack 123 is of the bar-likeform and of such a 'width that .the platen carriage may be movedrelatively-to the escapement dogs in a vertical direction withoutdisengagement-,1

of the dogs-and rack during the shift movement of the platen carriage..The dogs 121 and 122 are adapted to engage'the teeth of as rack ma itsmoveinput in the orin a'n preferred way, samd can'iage' being under etensionof the springer-ranged in a drum 125, there v :a flexibleconnection between said.

part. of the carriage tending transversely e escapement amen normally toforcethe' carria .of the machinefas usual.

' dogs, theremay be a limber and a fixed 1,0 dog if preferred, are notactuated during.

, the rearward movement of the universal bar, the part115 of the arm 113yielding during said rearward movement to pass by the am 119, but on thereturn movement '0 15, the universal bar the part,115 will actuate,

the escapement dogs to permit-the tension mechanism to force thecarriage the distance of a letter-space, said part 115 again passing tothe front ofthe-arm 119. The purpose of he 7 the escapement dogsoperated during t a return movement of the universal bar is to avoid thefeed movement of the carriage takin place'at or-about the time the tyfisis m 'ng its impression on the worka ut the platen. The universal bar isas herein stated held to move with the arms 106, and b havin said armslocated on o posite si es of t e longitudinal center of te machine auniform movement so, is given to the universal bar no matter which lever52 'is operated, the rod 112' which com nects the rods 110 being bentsubstantially centrally thereof, as at 126, so as not to mt'erfere withthe verticalrod 124 on which 86 the escapement detent 120 carrying ismounted. p

The escapement dogs are adapted to be operated bya' s ace bar 128 toletter spacei .pivoted to, a bracket on the frame'base part14, an d isnormally forcedin one d1- rection by a sprin 131. The upper endo the-arm181 1s a agted' to engage a down wardly extending ar orpart 132.. Thispart 132 is held to the universal bar and 65. when the space bar isdepressed so as to move the lever 130, the part 132 will be up eratedand will force the universal bar rearwardl and o crate the escapementdogsas valrea ydescri 5'0 The construction and operation ofthe inventionwill be readily understood from the fore oing description when taken inconnection with the accompanying drawings.

Assuming the parts to be in the position esfshown in Fig. 1, it will beapparent that 'riage bed to s their rearward movement forcing the typeto make an impression upon the work about "the platen. On the, releaseof the keys there typebars andparts-will be restored to their normaloperative position. As each lever 53 is operated the universal bar 104will f be, moved and by means ofthe vertical arm 113 the escapement dogswill be operated during the return movement of said arm, thus permittingthe carriage to move a let! ter space under the tension of the drum--125. The platen carriage may be shifted 'ior capitals and figures asalready described.

When the machine is to.bemade compact the platen carriage is moved alonthe carthe knobs within the side-walls 13 of the main frame part and thekeyboard frame art 20 is moved inwardly as shown in ig. 4. This inwardmovement off'the keyboard frame part will force the transverselyextending bar 92 upwardly and will cause the rods or links 99 to, rotatethe eccentrics'102, thus permitting the platen and carriage to lower toan inoperative I osition with respect to; the type. The en s 36 .of thecasing or frame may be moved to close theopen space 37 in the side walls13, and the top or cover 16 and front plate or member 18. may be movedto the sition shown in Fig. 4, In this position t e front plate andcover may be held by 'means ofthe lock 32, a which. time the mac ine isin condition for transportation, an .the parts concealed and protected.a

While one form of ribbon mechanism is, shown, such mechanism forms no pmof thepresent invention but is claimedin a separate application. l a
